FIG. 8 is a perspective view of the pressure transmitter in itsenvironment of use. In this figure, elements which are not a part of theclaim are illustrated in dotted lines.

The article is an apparatus for measuring a relative pressure, that is,a pressure after comparing an introduced pressure with an atmosphericpressure, vacuum pressure, or other source of pressure, and forconverting the pressure into an electrical signal sent to a remote site,and for indicating a value corresponding to the electric signal.

The horizontally long rectangle located in the middle upper part of thebody in the front view is a liquid crystal indicator, which indicates ameasured pressure value. The circle surrounding the liquid crystalindicator is made of transparent material, protecting the liquid crystalindicator and permitting viewing of information indicated on the liquidcrystal indicator from outside. The circles near the middle upper partof the body in each of the right and left side views are conduits forreceiving an electric power cable, for providing electric power to thearticle and also for transmitting the pressure signal out to the remotesite.

The central circles of the three small circles vertically aligned alongwith the respective right and left edges of the lower part of the bodyin the right and left side views are pressure ports for guiding liquidto be measured. When this article is installed, one of the pressureports shall be connected to a pipe where the liquid to be measured isrunning, while the other pressure port which is connected to the pipewill be closed.

CLAIM The ornamental design for a pressure transmitter, as shown anddescribed.
